Answer:
553/900
Step-by-step explanation:
x = 0.6144444........
Multiply both sides by 1000
1000x = 614.444.....
Multiply both sides by 100
100x = 61.444.....
Now subtract,
1000x = 614.444....
<u> 100x = 61.444.....</u>
900x = 553
x = 553/900
Answer:
the square root of -1/4 is irrational
8+(16)/4 (divide 16 and 4 first, PEMDAS)
8+4 (add these two together)
12
Answer:
82.88%
Step-by-step explanation:
Given that:
Mean (μ) = 16.7 pounds
Standard deviation (σ) = 3.8 pounds
Number of pounds eaten = 11.5 = x
P(11.5 ≥ x ≤11.5)
P(x ≤ 11.5) :
Zscore = (x - μ) / σ
Zscore = (11.5 - 16.7) / 3.8
Zscore = - 5. 2 / 3.8
Zscore = −1.368421
P(Z ≤ - 1.3684) = 0.085593 (Z probability calculator)
P(x ≥ 11.5) ;
Zscore = (x - μ) / σ
Zscore = (11.5 - 16.7) / 3.8
Zscore = - 5. 2 / 3.8
Zscore = −1.368421
P(Z ≥ - 1.3684) = 0.91441 (Z probability calculator)
P(Z ≥ - 1.3684) - P(Z ≤ - 1.3684)
0.91441 - 0.085593 = 0.828817
0.828817 * 100% = 82.88%
